Catalyst Biosciences Reports Fourth Quarter and Year-end 2021 Operating & Financial Results and Provides a Corporate Update

March 31, 2022

SOUTH SAN FRANCISCO, Calif., March 31, 2022 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (NASDAQ: CBIO) today announced its operating and financial results for the fourth quarter and year ended December 31, 2021 and provided a corporate update.

“In late 2021 we announced a strategic change in corporate strategy, pivoting from hemophilia to a highly promising complement therapeutics and protease medicines platform,” said Nassim Usman, Ph.D., president and chief executive officer of Catalyst. “This month, we re-acquired the full rights to CB 2782-PEG adding to our promising portfolio, which includes CB 4332 our enhanced CFI development candidate. Having the full rights to these two potentially best-in-class candidates in dry AMD provides another opportunity in our exploration of strategic alternatives that was announced in February. We are also implementing expense reduction measures, including headcount, while we continue this process.”

Recent Milestones

  • Regained the rights to CB 2782-PEG for the treatment of Dry AMD, expanding the Company’s complement portfolio in ophthalmology. With the full rights to CB 2782-PEG back under the company’s control, Catalyst now has two wholly owned, potentially best-in-class development candidates. Dry AMD is a leading cause of blindness in its severe form for which there are no currently approved drugs. The potential dry AMD market is estimated to be over $10 billion.

  • Received Rare Pediatric Disease Designation for CB 4332 for the treatment of CFI Deficiency. Under the FDA’s rare pediatric disease designation program, the FDA may grant a priority review voucher to a sponsor that received product approval for a rare pediatric disease. A rare pediatric disease is defined as a serious or life-threatening condition that affects less than 200,000 individuals in the U.S. per year and who are primarily less than 18 years of age.

  • Announced plans to explore strategic alternatives for the company.

  • Implemented further personnel and cost reductions, including additional headcount reductions of approximately 19 employees, or 70%, that are expected to be completed by April 30, 2022.

Fourth Quarter and Year-End 2021 Results and Financial Highlights

  • Cash, cash equivalents, and, investments, as of December 31, 2021, were $46.9 million.

  • Research and development expense for the three months and year ended December 31, 2021 was $16.1 million and $68.9 million respectively, compared with $14.6 million and $53.0 million for the prior year periods, respectively. The increase was due primarily to an increase in MarzAA clinical and manufacturing costs, preclinical research costs, personnel-related costs including one-time severance costs associated with our restructuring, and an increase in facilities costs.

  • General and administrative expense for the three months and year ended December 31, 2021 was $4.2 million and $19.0 million, respectively, compared with $4.3 million and $16.2 million, for the prior year periods, respectively. This increase was due primarily to an increase in personnel-related costs and an increase in professional services.

  • Interest and other income (expense), net for the three months and year ended December 31, 2021 was $(16,000) and $(39,000) respectively, compared with $(0.1) million and $1.1 million, for the prior year periods, respectively. The $1.2 million decrease was primarily due to a decrease in interest income and due to the payment received in the first quarter of 2020 under an agreement associated with neuronal nicotinic receptor asset sold in 2016.
  • Net loss attributable to common stockholders for the three months and year ended December 31, 2021 was $20.3 million, or ($0.65) per basic and diluted share, and $87.9 million, or ($2.87) per basic and diluted share, respectively, compared with $18.9 million, or ($0.86) per basic and diluted share, and $56.2 million, or ($2.93) per basic and diluted share, for the prior year periods, respectively.

About Catalyst Biosciences, the Protease Medicines company
Catalyst is a research and clinical development biopharmaceutical company focused on developing protease therapeutics to address unmet medical needs in disorders of the complement system. Proteases are natural regulators of this biological system. We engineer proteases to create improved or novel molecules to treat diseases that result from dysregulation of the complement cascade. Our complement pipeline consists of several proteases that regulate the complement cascade including CB 2782-PEG, a C3 degrader for the potential treatment of dry age-related macular degeneration (dAMD), improved Complement Factor I protease CB 4332 for patients with deficiencies in CFI including dAMD, and proteases from our ProTUNE™ C3b/C4b degrader and ImmunoTUNE™ C3a/C5a degrader platforms designed to target other disorders of the complement or inflammatory pathways.
